Publication Information, Warnings (Merge Publication, SQL Server 2005 and Later)

 

Applies To: SQL Server 2016

The Warnings tab is available for Distributors that are running SQL Server 2005 and later versions. The Warnings tab allows you to perform the following tasks for the selected publication:

  • Enable warnings.

  • Specify thresholds associated with warnings.

  • Define alerts associated with warnings.

By default, Replication Monitor displays warnings for uninitialized subscriptions: a status of Uninitialized subscription is displayed as a warning in the Status column of pages that include subscription information. For merge publications, you can specify whether these additional conditions result in warnings:

  • Imminent subscription expiration.

    This corresponds to the option Warn if a subscription will expire within the threshold. If the specified threshold is met or exceeded, the subscription status is displayed as Expiring soon/Expired (unless an issue with a higher priority needs to be displayed).

  • Exceeding the specified synchronization time.

    This corresponds to the options Warn if a merge length for dialup connections exceeds the threshold and Warn if a merge length for LAN connections exceeds the threshold. Both of these thresholds can be set, but only one is used during a given synchronization. The Merge Agent applies the appropriate threshold based on the connection type.

    If the specified threshold is met or exceeded, the subscription status is displayed as Long-running merge (unless an issue with a higher priority needs to be displayed).

  • Falling short of processing the specified number of rows in a given amount of time.

    This corresponds to the options Warn if rows merged per second for dialup connections is less than the threshold and Warn if a merge length for LAN connections exceeds the threshold. Both of these thresholds can be set, but only one is used during a given synchronization. The Merge Agent applies the appropriate threshold based on the connection type.

    If the specified threshold is met or exceeded, the subscription status is displayed as Performance critical (unless an issue with a higher priority needs to be displayed).

When you enable a warning, you also set a threshold. For example, if you enable the warning Warn if a merge length for LAN connections exceeds the threshold, set the maximum allowable length of time for a merge synchronization.

In addition to displaying a warning in Replication Monitor, reaching a threshold can also trigger an alert. Alerts are defined by clicking Configure Alerts and providing information in the Configure Replication Alerts dialog box.

Enabled
Select to enable a warning and specify a threshold.

Alert
